Briefly describes the battery short circuit testing machine external short circuit test requirements
1, normal temperature external short circuit test requirements: the battery in accordance with the prescribed test methods, placed in 20 ℃ & plusmn; 5 ℃ environment, to cell surface temperature of 20 ℃ & plusmn; After 5 ℃, 30 min. Then use wire connection battery positive and negative extreme, and ensure that all external resistance for 80 m & Omega; ± 20mΩ 。 Test in the process of monitoring the battery temperature change, when there is a one of the following two circumstances, the termination: a) Battery temperature down to about 20% lower than the peak b) A short time at 24 h. Test result: the battery should be no fire, no explosion, the highest temperature does not exceed 150 ℃. 2, high temperature and external short circuit test requirements: the battery in accordance with the prescribed test methods, placed in 55 ℃ & plusmn; 5 ℃ environment, to cell surface temperature of 55 ℃ & plusmn; After 5 ℃, 30 min. Then use wire connection battery positive and negative extreme, and ensure that all external resistance for 80 m & Omega; ± 20mΩ 。 Test in the process of monitoring the battery temperature change, when there is a one of the following two circumstances, the termination: a) Battery temperature down to about 20% lower than the peak b) A short time at 24 h. Test result: the battery should be no fire, no explosion, the highest temperature does not exceed 150 ℃. 3, short circuit protection: the sample test for 500 cycles in the following order: a) Short circuit battery positive and negative of extreme or protection circuit output terminals; b） The protective device let stand for 1 min. When short circuit and external short circuit the total resistance is 80 m & Omega; ± 20mΩ 。 Each cycle when the battery short-circuit protection circuit should be action. When the sample is battery test before a full charge in accordance with the relevant provisions of test method. And shall ensure that the battery pack in the process of test, a 500 - cycle test is under the state has not put up electricity, if the battery pack before the test for the 500 cycles has put the electricity, the battery should be in accordance with the prescribed test methods, test to continue the cycle.

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.
Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.
Pneumatic Method (ISO 13938.2): Compressed air for breathable materials tested with GT-C12B.
Results are influenced by raw materials, yarn properties,
Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
